What are the advantages and disadvantages of using CSV files in PHP for data storage?

Using CSV files in PHP for data storage can be advantageous because they are easy to read and write, widely supported, and can be easily imported into spreadsheet software. However, they may not be suitable for storing complex data structures, can be inefficient for large datasets, and may not offer the same level of security as a database management system.

// Example of writing data to a CSV file
$data = [
    ['John', 'Doe', '30'],
    ['Jane', 'Smith', '25'],
    ['Tom', 'Brown', '35']
];

$fp = fopen('data.csv', 'w');

foreach ($data as $fields) {
    fputcsv($fp, $fields);
}

fclose($fp);
